Mystic — The Hampton Inn has been shut down after a sprinkler pipe froze and broke in the building’s attic this morning, causing extensive water damage.

The hotel will remain closed while repairs are underway, according to Old Mystic Fire Chief Ken Richards.

No one was injured, but the broken pipe cause water damage to the first, second and third floors of the building, said Richards Sunday morning.

Richards said approximately 30 guest rooms at the hotel, which is located at Hendel Drive and Route 27, were affected by the broken pipe and six were severely damaged. All guests have been moved to other local hotels, he said.

Old Mystic firefighters were originally called to the hotel at 4:50 a.m. to check out an odor of something burning but did not find anything. Another alarm came in at 7:42 a.m., at which time they found water damage to the ceiling.

The firefighters were still on scene at 11 a.m., moving in and out of a hotel lobby littered with pieces of crumbled dry wall. Water dripped from the lobby’s ceiling.

Specialized equipment for water removal was called in from Mystic Fire Department, Quiambaug Fire Company, Oswegatchie Waterford Fire Department, Montville Fire Department and Niantic Fire Department, according to Richards.
